Thread-topic: [PATCH] Optimizing x86-64 xenlinux using global pages for user mode (take 2)
The previous patch had a problem with the builder, which constructs the
initial page tables with the USER bit on. And Xen couldn't distinguish
kernel or use pages. It was partially checked avoiding the bug, and it's
finished with this patch.
